PATENT I FI Q "To all'whom it mayoohcern: r

Beit known that I, OsoARG. HAMEL, a citizen of the United States, residing at Peabody, in the county of Essexand State of Massachusetts, have invented certain new and "useful Improvements in Gearing, of

' which the following is a'specification. I

''This invention relates to driving gearing, and has for one of its objects to produce a device whereby'zthe power to produce the re-' qu'ired motion is reduced, without :decrea'sing the efiiciency of the'appar'atus;

' 'Another object of theinvention is to produce 'a device of'thls character in whlch provision is made for operat ng the moving parts in an inclosing oil holding casing, to prevent noise and to secure the necessary lubrication; 1

Another object of the'invention'isto provide a device of this character including a supporting frame in two p ortions',one portion to supporta rotative means, and'the other portion supporting speed controlling means together with a receptacle for a lubri- I cant inwhich the speed controlling gearing constantly rotates. I 1' 1 With theseand other objects in view, the

invention consists in certain novel features of construction as hereinafter shown and described and-then specifically pointed out in the claims hereunto appended, and in the drawings illustrative of the preferred embodiment of the invention.

In the accompanying drawings: I I 'Figurelis a side elevation with the combined cover and. cap member in position, I

' Fig.2 is a plan view partly in section with the combined cover for the oil chamber and shaft cap member detached,

'Fig. 3 is an end elevation, I r

Fig. 1 is a plan view of the oil chamber cover andshaft caps.

The improved device comprises an oblong open frame includinglongitudinal members 10.11 and endmembers 12 and 13. The side memberslO and 11 of'the frame are connected. by an intermediate transverse member 13' thus dividing the frame into two portions, a relativel large and a relatively small portion as S own. H V

The frame member 12 is provided with a half bearing 14 and a cap 15, for one end of a tubular'shaft 16, while the intermediate frame member 13 is provided with a Similar half bearing 17 and cap 18 for the same tubular shaft, the tubular shaft being Specification of Letters Patent. Patented Sept,-

fippl icat'ion rne'dIAu ust 4, 1920. Serial no; 401,122 r "formed with an intermediate oil chamber or reservoir indicated at 19. f The shaft 16 supports drive pulleys 20 operating within the larger frame portion, as shown. 7 I

Formed integral with the framemember 13 and depending below the Same is a half casing for pocket 21 for a lubricating ele ment Extending from the outer side of the half casing 21' is a half bearing 23, and formed in the frame member 13' are half bearings 24 and 25 tos'upport a counter shaft 26.

Bearing over the half. casing j 21 is the other half of the' casingrepresented at 27 and having flanges 28 and cap 29-corre-- spending to 'and coacting with the portion of the frame members which encompass the i I 775 The casing member 27"is. secured'by bolts half casing 21.

30 through: the :flange 28 I and "by bolts 31 throughthe flanges of the "half be'arings 23 The, casing members21 and '27xconstitute a reservoir for lubricating 'oilfor the gear-,

The tubular shaft 16 extends into the oil reservoir and is provided with a gear 32,

preferably integral with'the shaft, and operating within the reservoir.

ing, and the: joint between'the flanges be suitably packed to prevent theescape of end in the tubular'shaft 16 externally of oil chamber 19, and likewise Supported by the hub; portion of the gear 32.

At one end the shaft33' extends through bearing 2329 and beyond the same and is adapted to receive a gear,- belt pulley, or the like, whereby power is transmitted from or to the shaft. I

Mounted on' the shaft 33 within the oil reservoir or casing 2127. is a" larger gear 34, and mounted on the counter shaft 26 are I pinions 35 and 36 ofunequal diameter en-..

gaging respectively with the gears 32 and 34. a

' The flange frame members 10 and 11 are provided with supporting lugs 37 perforated to receive holding bolts 38. whereby the apparatus may be attached to a suitable sup- .port, represented conventionallyat 39.

With an apparatus thus constructed it will be obvious that motion imparted to the pulleys 20 or to the shaft 33 as the case i other with materially increased or decreased may be,,willbe transmitted from one to the torque, or increased or v deereased speed. For instance, if the motion is imparted to the shaft 33, this motion will betransmitted to the pulleys at somewhat increased speed,- and if the motion be imparted'to-V the pulleys 20, the motionwill be transmittedto the shaft 33'and the pulley or gear connected thereto at decreased speed but I with increased torque.

The largeriframe portion operates to support thepulley bearing portion of thetubular shaft,-while the tubular shaft-in turn supports the drivergshaft 33. i

, The end member 1270f the frame is therefore an important feature of the apparatus and insures a uniform support for the tubular shaft andthe internal shaft at their outer ends, andprevents unequal movement during the operation; 5 r
